TLDR summary: run "c_rehash" as root to fix this issue. I just ran into this issue (symptoms: "wget https://ev- root.digicert.com/", "openssl c_client ev-root.digicert.com" would fail) .
The problem is that the symbolic links that are supposed to exist in /etc/ssl/certs aren't there. Running "c_rehash" command recreates the links . Reinstallling ca-certificates does not fix this issue, because /usr/sbin/update-ca-certificates only runs c_rehash when /etc/ssl/certs /ca-certificates.crt is out of date (ie. when you added or removed some certificates). I don't know why an Ubuntu 12.04 LTS system would be in this state, perhaps it only happens on systems that were upgraded from earlier Ubuntu installs, and for some reason c_rehash never got run. $ wget https://ev-root.digicert.com/ --2013-06-07 19:55:03-- https://ev-root.digicert.com/ Resolving ev-root.digicert.com (ev-root.digicert.com)... 64.58.225.123 Connecting to ev-root.digicert.com (ev-root.digicert.com)|64.58.225.123|:443... connected.
